Purpose: determining appropriate components to assess the status of the children and adolescents in the country's public libraries.
Method: This applied study was conducted using a mixed-method survey-analytical method. In the quantitative part, library and document studies were used to collect data and design researcher-made questionnaires. In the qualitative section, the Delphi method was used to review and confirm the components extracted from the quantitative section with the opinions of seventeen members of the expert panel. Data analysis was performed with SPSS software using descriptive statistics and inferential statistics (Kendall, Friedman, and Chi-square tests).
Results: The findings showed that with the Kendall coordination coefficient (0.294) in the fourth Delphi stage, relative consensus among members was achieved and all 33 indicators in 6 components were above the total average. The Friedman test showed a significant difference between the highest ratio related to "equipping the library with tables, chairs, and ergonomic furniture for children and adolescents" (4.59) and the lowest ratio related to "planning counseling services for adolescents" (3.06). Also, the priorities of the components were most related to "library factors" (33.71) and the least related to "library environmental factors" (10.71).
Conclusion: Scientific and authoritative studies, including 33 indicators in 6 categories, have been compiled and approved based on the institution's services, specialized human capital, and intellectual development in improving the quality of children's and adolescents' libraries, which can serve as a practical and managerial guide for decision-makers and managers to improve and develop this and play an important role in developing a reading culture.
